Water is one of our most vital sources on the planet. It’s all around us; 70% of the human brain is water, and there are roughly 326 million trillion gallons of water on Earth! As one of our most important resources, and with growing populations and more and more need for water everyday, it is vital that we protect this shared resource for future generations.

One of our partners here at Filters.com is Suez Environment, a world leader in water treatment. They recently put together a really inspiring YouTube video about how they’re working to revolutionize and digitize the way that we clean water. Watch the video below to hear them talking about why they love their work, but more important what its impact has on the water supply in the world. We are so excited that our filters are used by Suez and that we are a part of making the world’s water supply cleaner!

There are a few rules to remember when sizing a filtration system:

Differential

  • With in-depth cartridge filters, the slower the flow, the more efficient the cartridge is and the longer the user can go between change-outs. At Filters.com, we typically size housings to start out with a clean differential pressure of two pounds or less. You will find that many people in the filter business will quote housings that are undersized for an application so that they quote the lowest capital equipment cost.

 

  • The differential pressure (pressure drop) across both the cartridge and housing must be considered cumulatively. The pressure drop across the housing differs from housing to housing, but in most cases, it can be obtained from the housing manufacturer.

 

  • Assuming a cartridge vessel is designed for cartridges with a one-inch inside diameter, keep in mind that the flow through the bottom of each filter should not exceed 15-25 gallons per minute (for membrane pre-filters, try not to exceed 15 gpm). These flow rates should not be exceeded because turbulent flow is created on the interior core of the filter, which frequently cause unloading of contaminant from the filter media.

 

  • Always consider the viscosity of the material to be filtered when sizing filters or vessels. Also keep in mind that the viscosity of most materials varies depending on temperature. If you have an application where the customer does not want to go over a certain differential pressure and the temperature of the product can go through a wide swing, be careful to find out what the viscosity of the liquid is at both extremes of temperature.
